I hate everyone else in the AFC East
Starks and langford are core. Smith and Davis are core. Long and Carey at tackle are core. I think Grove is core. Guards I feel like can be replaced easier but very good centers are hard to find. I hope Henne is core.
We are missing a core TE, core WR, and a core safety. Every great defense in the league right now has a great safety, Reed, Troy P, Bob Sanders ( not a great d but totally different with him in), it is such an important position. With Troy and Bob out those Defenses aren't nearly as good.
